I have had 2 no start situations in the last month. The first I was in a hurry and figured I had not allowed enough time for the glow plugs to heat up. It started second try.... The other no start situation was just a week ago, it wouldn't start after 2 attempts, I pulled they key out of the ignition, put it back in and it started fine. As it was still a somewhat isolated incident and was showing no other symptoms of anything being wrong, I thought nothing of it.
